Retrorse means pointing or turned backward. Think of a cat's claws when they are retracted, or a fish's scales that lie flat against its body heading towards the tail. It’s often used in botany to describe hairs, barbs, or other plant parts that point back towards the base of the stem or branch. So, retrorse is the opposite of antrorse. Imagine a street sign pointing the wrong way; that's retrorse!
